3. Block Out the Din
Rather than nagging co-workers to lower their phone voices, shut them out entirely. Get a good pair of noise-isolating earphones, like the KEB79 earbuds from Koss, which have a mute clicker on the cable for when you do want to hear your neighbors ($70 at J&R Electronics, 31 Park Row, nr. Beekman St.; 212-238-9000).

4. Be the All-Seeing Eye
A rear-view mirror on your monitor not only warns you when your boss is approaching, but it’s also supposedly good feng shui ($14 from Spoonsisters.com).

6. Add an Oddity
“Things around you should bring a smile to your face,” says Ann Bingley Gallops, New York president of the National Association of Professional Organizers. Mika Kim’s porcupine paper-clip holder might just do the trick. ($20 at MoMA Design Store, 11 W. 53rd St., nr. Fifth Ave.; 212-708-9700).

8. Sit Right
For aching backs, Dr. Josh Handt, a chiropractor at the New York Chiropractic Life Center, recommends the Back Vitalizer, which looks like your average chair cushion but keeps your back far more mobile. “A body that’s not in motion is more vulnerable to injury,” says Handt ($60 at Backvitalizer.com).

9. Feel the Breeze
A small fan under your desk creates a little bit of white noise and helps circulate air flow—always good for general health (Vornado Zippi fan, $20, at gracioushome.com).
